r useful Improvements in Automatic Locks for Windows, of which the following is a speciiication.

This invention relates to improvements in means for securing the sashes of ordinary windows in a locked position, one relative to the other, and its principal object is to provide means which may be operated from the interior, positively locking one of the window sashes with the other, and having means combined which tend to draw the two sashes toward each other.

A further object is to provide such devices in forms which are lnexpensive to manufacture, readily applied to window sashes of ordinary construction, and which may be operated by any person without previous experience.

These and like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 1s a partial vertical sectional view showing a pair of sashes in an un- 'Y locked position.

Fig. 2 is a similar view of the same showing the sashes in a locked or engaged position.

Fig. 3 is an enlarged fragmental sectional view showing the same construction as that disclosed in Fig. 2.

Fig. 4 is a transverse sectional view taken on line 4`4 of Fig. 3.

Fig. 5 is a similar transverse sectional view taken on line 5-5 of Fig. 3, but showing the bolt retracted, and

Fig. 6 is a side elevational view showing the device as it appears when applied to the window Sash, parts being removed to show the construction.

In Figs. 1 and 2, the lower portion of a complete window frame is shown containing the lower member 11 of the upper outer sash, the corresponding lower element 12 of the lower inner sash resting upon the sill 10 in the usual manner, the disposition being so that the upper element 14 of the lower sash is positioned closely adjacent to the sash 11, when the windows are in a closed position,

and in order to lock the same against movement when in such position an opening 15 is formed in the lower member of the upper sash element, the opening being covered by a plate 16, held to the sash lby means of the screws 17, the plate being provided with an elongated rectangular aperture 18 leading directly to the recess 15.

In the upper element 14 of the inner sash is a through opening 20 having on the inner side an enlarged or counterbored portion 21 in which is rigidly aiixed an annular casing 22 provided with a anged base 23 from which extends a cylindrical sleeve 24, the flange being secured by screws 25, and surrounding the sleeve 24 is a tubular element 28 attached to a hollow stem 29 which extends outwardly beyond the sash, and is provided with a disk 30 at its head by means of which the sleeve 28 may be drawn outwardly through the bushing 31, having a flange 32 secured by screws 33 to the lower sash.

Engaged rigidly within the tubular sleeve 29 and held to the head 30 by the screw 35, is a bolt 36 slidable within the sleeve 24 and provided with a T shaped head 38 adapted to pass through the opening 18 in the plate 16, and to be turned therein by manipulating the disk 30, thereby engaging at the rear side with the plate 16 in such manner as to prevent its being withdrawn except the disk 30 be further turned.

In addition, a coiled spring 39 surrounds the bolt 36 and exerts pressure between the end of the sleeve 24 and the shoulder formed within the hollow stem 29, the spring tending to press the disk 30 outwardly and at the same time to exert a considerable tension upon the elongated rectangular bolt head 38, causing the sash elements to be drawn firmly together, thereby avoiding the passage of air or the like, and binding` the two sashes so that neither one can be moved without the disk be turned to free the bolt.

The construction, application, and use will be evident from the foregoing description and drawings which disclose an eective device for the purpose mentioned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1 In a device as described, in combination, a window sash having an opening through one side thereof and having an enlarged portion at the opposite side thereof, an annu ar casing fitti-ng sii-ugly in said enlarged porti-on of said opening and having a cylindrical sleeve projecting concentri'cal'ly into vsaid opening, said casing being secured against displacement from said sash, a tubular element snugly and slidably iifing opem ing and telescoping over said sleeve, said element having4 a lfedllced hollow stem,v a-

bolt projecting into said sleeve and into said hollow stem, a disk formed' pon the oltci" end of said stem, providing` a handle and secured to` said bolt, a spring coiled arond said bolt, lting' said tuhu'lai element and mf@ cents emi, by addressing the wesmngtan, n; cz

bealin'o respectively against the inner edges of said sleeve and reduced stem, and a T- shaped head foiii'ned terminally upon said bol-t, said spii'nfg normally disposing said head Within said casing and spacing said dfiskf outwardly from said sash, and Coper# ating locking means upon an adjacent sash ada-plied to be engaged by the T-,shfape'dv head on the bolt. j
